As this is a brand new forum, I thought I'd open up a thread to encourage new members to introduce themselves a bit.. now hey.. let's not get too personal.. ok ?
And if you wouldn't mind to keep this thread \"clean\" let's try to keep the the chitchat (i.e. even the welcome to the board replies) to a minimum or this thread may get to 100 pages fast
So I'll start things off :
My name is petabyte and I'm a forum junkie. :oops:
I've been off the wagon for a number of years and countless times I've tried to stop but it's useless.....

I'm designing an ESP-based WLED controller board for WS2815 12V LED strips, with a primary focus on energy efficiency.
To minimize power consumption, my goal is to completely shut down the system when the LED strip is turned off.
However, the current buck converter powering the ESP module draws about 8 watts even when the LEDs are idle, making it unsuitable for low-power operation.
I am using below components:- Buck Converter: TPS562201 (12V → 5V regulated)
- Microcontroller: XIAO ESP32-C3 (with built-in USB-C)
- LED Strip: WS2815 (12V digital LED strip)
- Switching
